I feel that I am closing in on my optimum pressures but have stumbled upon a new puzzle and don't know which adjustment might be correct.
My AHI's are almost always under 3, 30 day average is 1.88, but some days I wake up feeling rested and some days I don't. I suspect because of RERA's.
Over the last few months I have slowly raised my EPAP, IPAP and PS to my current settings of EPAP 8.5, IPAP 15, PS 2-6.
My avg's for last week were EPAP avg was 8.52 and max was 9.5. Avg IPAP was 11.88 max of 15 and 90% 14.7.
I am primarily a back sleeper because of other issues that prevent me from sleeping on either side for extended periods of time.
My partner has been noticing a light snoring sound on inhalation sometimes resolved with an arousal, sometimes it continues. I know this is happening when I first fall asleep, what I don't know is if it continues all night.
I am not sure about is if my airway is partially collapsed because my EPAP is too low or if my IPAP is too low or are both reasonable and I just need to increase my pressure support. Is my pressure too low when I first fall asleep while waiting for my machine to increase PS?
I have continued to raise my EPAP pressure as I have raised my IPAP pressure even though my EPAP pressures are normally near my minimum pressure. Should I not continue to raise EPAP?
The majority of my events are Flow restrictions, RERA's and Hypopneas.
I am happy to provide any additional sleepy head data, not sure what would be most helpful.
Thanks to all who take the time to read and offer suggestions.
